Orbi RB50 assigning IPs out of range, wrong connect types
Anybody have any ideas? I've had years of no-hassle use from my Orbi system, but I'm at wit's end with current troubles. I have an RBR50 with satelites RBS50 and RBW30, connected to Comcast upstream...

It is 99.999% certain that the Orbi is not assigning IP addresses that begin with anything besides 192.168.1.
So, either:
- devices are configured with static IP's that begin with 172, or
- some other DHCP server is giving out these addresses
You would probably remember assigning static IP's, so my money is on another DHCP server. Likely culprits include NAS servers and media devices. Some smart speaker systems attempt to network themselves.
I positively love capturing packets and looking at them with Wireshark, which puts me squarely in the uber nerd category.
Another simplistic question is, "what has been added to the network since things were fine?"
Has a factory reset and setup from scratch been performed since last FW update?
What Firmware version is currently loaded?
172s would not be coming from the RBR if you have setup the RBR for 192.
Afer a factory reset of the RBR and power cyle OFF of the ISP modem, set up the RBR off line from the modem and ALL other devices. Setup the IP address range from 192.168.1.100 to .200. You might even try using 192.168.0.1 as a different submet pool. .0.100 to .200.
Either one, then after it's setup, connect the RBR to the modem and connect just 1 wired PC to the RBR. Turn both ON and check the connections and such. Check for IP addressing on the connected devices page on the RBR.
Start graduating adding devices either 1 at a time or 2-3 at a time. Again checking connected devices page for IP addressing.
Make sure that you don't have any devices that have any kind of static configured IP addresses set ON the device. Static IP addresses are set ON devices, not the router. IP address reservations are set ON the router and not on devices.
no, didn't do factory reset. thanks for the steps... i'm hoping it doesn't come to that... sounds painful :)
